Chemical reactions involving solids work on the surface of the solid. A fine powder has more surface area than big lumps.
Carbonates would generally react faster as powder compared to lumps due to the increased surface area available for the reaction to occur. More surface area allows for more contact between the reactants and speeds up the reaction process.
Medium-sized lumps of a chemical substance typically refer to aggregates or granules that fall between fine powders and larger chunks. These lumps can vary in size depending on the material and its intended application, such as in pharmaceuticals, agriculture, or industrial processes. They often result from the crystallization, drying, or processing of chemicals and can influence the substance's solubility, reactivity, and handling characteristics.
Powder should not be used in boiling water because it can clump together and form lumps, making it difficult to dissolve evenly. It can also create a mess and increase the risk of burns if it splashes. It's better to dissolve the powder in a small amount of cold water first before adding it to boiling water.
Yes, the process that removes lumps from an ingredient is called sieving or sifting. This technique involves passing the ingredient through a mesh or screen to break up clumps and ensure a fine, uniform texture. It is commonly used with dry ingredients like flour, cocoa powder, and sugar to improve their consistency and mixability in recipes.
To dissolve locust bean gum powder into a solution, gradually sprinkle the powder into warm water while stirring continuously. Allow the mixture to sit and hydrate for a few hours or overnight, stirring occasionally until it forms a smooth, thick solution. Heating the solution slightly can help dissolve the powder more quickly.
Carbonates would generally react faster as powder compared to lumps due to the increased surface area available for the reaction to occur. More surface area allows for more contact between the reactants and speeds up the reaction process.
Powder typically has a larger surface area compared to lumps because the fine particles in powder allow for more surface area to be exposed. This increased surface area can be advantageous for processes like absorption or dissolution.
powder form
The medium-sized lumps of a substance are called granules. Granules are intermediate in size between powder and larger aggregates or chunks.
Carbonate in powder form would react faster than in lump form because the powder has a larger surface area, allowing for more interactions with the reacting substances. This increased surface area facilitates quicker reactions by providing more opportunities for collision between molecules and speeding up the reaction process.
To make a delicious gravy without using flour, you can use cornstarch or arrowroot powder as a thickening agent instead. Mix either of these with cold water before adding them to your gravy to prevent lumps.
All sorts of things can cause lumps. Bruises, insect bites among others. If you are worried you should see a doctor.
when coal is pulvorised(powder ) the surface area will be more so it cathes fire early than lumps.
The reaction is slower because lumps were used instead of smaller pieces thus the surface area is small and so the acid has less space to act on and the ice decreases the temperature, the higher the temperature the faster the reactions
No. The flour stays chemically the same. Sifting mixes air with the flour and breaks up lumps.
BaO is the formula for Barium Oxide. ( aka, barium monoxide or protoxide ... calcined baryta) BaO is white to yellowish-white lumps or powder. It is POISONOUS !!!
